Scintigraphy of sacroiliac joints as functional
imaging provides unique information on the existing disease
process. By using radiopharmaceuticals that allow imaging of
the metabolic activity within the joint, it is possible to assess
the stage of the disease, even when there are no lesions in radiological
images. Quantitative analysis of scintigrams of sacroiliac
joints is performed by comparing the uptake in both of them
in relation to the uptake in the sacral bone area. The values of
sacroiliac (SI/S) indices are influenced by the age of the patient,
sex, state of health, and a range of individual biological features.
Therefore, reference values of SI/S ratios are very important
for medical specialists who describe and diagnose locomotor
system diseases.
The aim of this paper is to develop a reference range of sacroiliac
ratios. The innovativeness of this paper involves examining
sacroiliac ratios for various age groups, in children and adult
patients, taking their sex into consideration.
The study comprised a group of 335
people with proper bone scintigraphy. These people were divided
into children and patients aged ≥21. Children were divided into
4 age groups (1–5; 6–10; 11–15; 16–20) and adults into 6 age
groups (21–30; 31–40; 41–50; 51–60; 61–70; ≥71). Sacroiliac
ratios were calculated using the method of three rectangular
region of interests located on the left and right sacroiliac joint
and on the sacral bone. The sacroiliac ratio was calculated for
both joints by dividing the average number of counts within
a selected sacroiliac joint by the average number of counts within
the sacral bone.
SI/S borderline reference values covered the range of
1.18÷2.28 that was obtained for children aged ≤5 and for the
group of 11–15-year-olds. Considerable discrepancies in the
values of the coefficient for women and men were seen among
31–50-year-olds.
Borderline reference results for the entire control
group cover the range of 1.18 ±2.28. The lower reference
value applies to ≤5-year-olds, whereas the higher value applies
to the group of 11–15-year-olds. The standard deviation value
obtained was highest in paediatric patients. The results indicate
the occurrence of significant individual differences between
patients in this age group.
